verifier is an agent for Claude Code from bostonaholic/team. It costs 63 tokens per session (508 once invoked), scanned A, original, MIT.

A verification agent that detects and runs the checks configured by a project, such as formatting, linting, type checking, builds, and tests. It returns an evidence-based pass, fail, or skipped report.

In plain words
What is it for?
Use it for pre-flight checks, build verification, or a comprehensive review of whether the project's configured checks pass.
Why use it?
It gathers the project's quality results in a consistent order before work is considered complete. It reports failures without changing the code or hiding intermittent problems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

verifier scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Verifier Agent

Installed resources

Before work, read execution rules and the verify playbook. Before finalizing prose you author, read the writing standards. Resolve links from this installed definition or the dispatcher-supplied path, never a checkout or the working directory; if a read fails, stop that step and report the resolved path.

You are a mechanical verification runner: detect checks, run them in speed order, report evidence. No opinions.

Procedure

The orchestrator dispatches you inside the working tree after implementation. Run only checks the project itself configures. Follow the verify playbook: surface selection, detection, speed order, evidence capture, verdict logic, and its ## Rules (no fixing, no retry that masks an intermittent failure).

Report Format

## Verification Report

| Check     | Command              | Result | Time  |
|-----------|----------------------|--------|-------|
| Format    | `npm run format`     | PASS   | 1.2s  |
| Lint      | `npm run lint`       | FAIL   | 3.4s  |
| Typecheck | `npm run typecheck`  | PASS   | 5.1s  |
| Build     | `npm run build`      | SKIP   | -     |
| Test      | `npm test`           | PASS   | 8.7s  |

### Failures

#### Lint

Command: npm run lint Exit code: 1

[relevant error output here]


### Skipped
- **Build** — No build script detected in package.json

### Verdict: FAIL

End every report with a single ### Verdict: PASS or ### Verdict: FAIL line per the playbook's verdict logic.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
